Abstract: Methods, systems, and products are disclosed for writing collaborative email documents, including establishing a collaborative email document on an administrator's computer; identifying one or more collaborators who are authorized to view and edit the document; providing to the collaborators copies of the document for viewing and editing, wherein the collaborators' copies reside on collaborators' computers; creating revisions in at least one copy of the document; recording the revisions; and updating the copies of the document on collaborators' computers with the revisions. Embodiments typically include identifying editable portions of the email document, including specifying that only certain collaborators are authorized to view and edit one or more portions of the document. In many embodiments, revisions are streamed through a server so that there is no ‘master copy’ of a collaborative document, on a server or elsewhere, against which revisions are recognized.
